Ingredients

• 4 (6 ounce) yellowfin tuna steaks

• ½ cup vegetable oil

• ⅓ cup soy sauce

• ¼ cup fresh lemon juice

• 2 teaspoons Dijon mustard

• 1 teaspoon grated lemon peel

• 1 clove garlic, crushed

• 4 wedges of lemon for garnish

Directions

1. Prick tuna steaks all over with a fork and place in a shallow glass baking dish.

2. Whisk together oil, soy sauce, lemon juice, Dijon mustard, lemon peel, and garlic in a bowl. Pour over tuna steaks. Cover the dish with plastic wrap and refrigerate for 1 to 3 hours.

3. Preheat the grill to medium heat and lightly oil the grate. Remove tuna from marinade; shake excess marinade from steaks and transfer to a plate.

4. Pour marinade into a small saucepan; bring to a boil. Reduce heat to medium-low and simmer marinade for 10 minutes.

5. Cook tuna on the preheated grill, basting with boiled marinade, until cooked through, 5 to 6 minutes per side. Serve with lemon wedges.
